

TEST CIRCUIT

Note:

Input capacitor (CIN): 1.0 μF or more

Output capacitor (CL): 2.2μF or more (tantalum capacitor)



SELECTION OF OUTPUT CAPACITOR (CL)

In this IC, phase compensation and the output capacitor is made for securing stable operation even if the load

current is varied. Therefore, always place a capacitor (CL) of 2.2 μF or more between VOUT and VSS pins. Using a

capacitor whose ESR is outside the optimum range (approximately 0.5 ~ 5Ω), whether larger or smaller, may cause

an unstable output, resulting in oscillation. For this reason, a tantalum electrolytic capacitor is recommended.
